项目摘要

All the bodily motions, including physical motion, can be put into the three dimensional coordinates. Recent remarkable development of personal computers enabled more precise graphics and improvement of computing speed, which has made it possible to draw up more complicated 3D graphics on the display.That is why we authors, intending to make the gathering of experimental data easier and the analyzes more precise, tried to develop a new skill-analyzing system with the introduction of 'the single point perspective transformation' and ' 360 degree turning ofa motion model'. Thanks to the development of electronic equipment, 3D analyzes have now evolved form stick picture into surface models, which greatly contributed to the 3D analysis in the field of Athletics.The originality of this research consists in that a motion model can be turned around 360 degrees and its from any direction, and this way of observation has turned out to be use, especially in sports in which the beauty of from and effective movements are considered important. Motion can be classified into two patterns ; the movement from one place to another and that on the spot or in a small area. Picking up 'skiing' from the former and 'golf' from the latter as a model case, we experimented under this system with analyzing the data we gathered, and dould obtain a fair success as to the application of this system.

所有的身体运动，包括物理运动，都可以放入三维坐标中。最近个人计算机的显着发展使图形更加精确，计算速度也得到了提高，这使得在显示器上绘制更加复杂的3D图形成为可能。因此，我们作者为了使实验数据的收集更加容易，分析更加精确，尝试开发一种新的技能分析系统，引入“单点透视变换”和“运动模型的360度旋转”。由于电子设备的发展，3D分析已经从棒图发展到平面模型，这对田径领域的3D分析做出了巨大的贡献。这项研究的独创性在于，运动模型可以360度旋转，并且可以从任何方向进行观察，这种观察方式已经被证明是有用的，特别是在重视动作美感和有效动作的运动中。运动可分为两种模式；从一个地方到另一个地方的移动以及在现场或小范围内的移动。我们以前者的“滑雪”和后者的“高尔夫”为典型案例，在该系统下进行了实验，并分析了收集到的数据，该系统的应用取得了一定的成功。
